Loop Powered Process Indicator Contrec 250 Loop Powered Process Indicator

Contrec process indicators are the ideal solution to accurately monitor and control your processes.

Our 250 programmable process indicators accept a 4-20mA loop signal from a wide range of transducers allowing the process indicator to monitor temperature, pressure, density, humidity, PH, level , energy and weight and many more engineering variables.  The indicator features an easy to read bar graph in addition to the large numeric display.

Our 150 Instrument provides an economical solution designed for non-hazardous area applications.

The indicators are powered entirely from a 4-20 current loop so therefore don’t require any external power or batteries. All parameters are stored in a 10 year non-volatile memory should the loop supply fail.
